Ever since high school science classes, Josh and Lucy's friendship has endured thanks to their mutual love of music and their tight-knit friendship group. Lucy relies on him for moral support through all her terrible relationship choices; while she searches for affection in all the wrong places, he remains the friend who stays, listens, and picks up the pieces. But what she doesn't know is that Josh has loved her right from the beginning - quietly, hopelessly and always from the sidelines.

When Lucy falls for Michael - charismatic, but impossible to pin down - she is drawn into yet another relationship that Josh can see will end in disaster, and he is once more left to navigate their mutual misunderstandings and the agony of loving someone who only sees him when everything else falls apart.

Told through shifting perspectives, One Way Street explores unrequited love, self-sacrifice and the quiet ways people hurt each other without meaning to do so.
